Neuroscience, which is a part of our daily life, has provided us with an incredible fascination with the human brain. All of our thoughts and dreams, memories and experiences arise from neural tissue.
In this journey that we started based on the developing world of science, a few decades ago, it was thought that brain development was largely completed at the end of childhood. We also know that the construction process of the human brain lasts until the end of twenty-five years of age. In our teens, the process of reorganization and change that brain networks undergo seriously shapes our apparent identity. These changes are gradually related to the self and the self-consciousness that accompanies it. As a result of the research, social situations and experiences increase as we move from childhood to adolescence, reaching its peak at the age of fifteen. An adult brain, on the other hand, has started to get used to it, just like a new shoe, it has fallen into place and become familiar, so to speak. At the age of twenty-five, the cerebral transformations specific to childhood and adolescence are finally completed. The end of these changes in our identity and personality may cause us to think that they are fixed and unchangeable, but this is contrary to popular belief. So, if the changes in our brain change as a result of a disease or an injury, do they change our personality or behavior?
In 1966, Charles Whitman went up to the observation floor of the tower and then started shooting randomly at civilians below, killing thirteen people. and was shot and killed by the police in the incident in which thirty-five people were injured. The situation regarding this incident was that Charles Whitman did not give any clue that he would commit such an action. Although he was an educated person and had not been involved in any violence in the past, he recently felt that he had unusual and irrational thoughts, and after his death, an autopsy was performed and he wondered about a series of facts that he could not understand. As a result of the autopsy, a small brain tumor was detected, and this tumor put pressure on the amygdala, allowing the structure related to fear and aggression to emerge. Our brain and body are part of our lives. Greek language is constantly changing and changing. Perceiving these changes becomes more difficult for us as human beings due to the speed at which we perceive them.
So who is in control? Let's look for an answer to the question...
Let's think of a point where we do our daily work. We get up in the morning, wash our hands and face, head towards the kitchen and brew our tea. Then we take the breakfast dishes out of the fridge and go to the stove to make melemen. We are aware that all these events in our lives are due to our needs, desires and are planned. To what extent can this conscious awareness control us? In fact, the brain is at work unconsciously. To give an example, you are drinking tea in a café and it is full of people you are chatting with. From the moment you lift your tea glass, my memory of the environments I have experienced before is activated again. The frontal cortex sends signals to the motor cortex. This is the region that coordinates the muscles that will come into play in my trunk, arm and hand to grasp the glass. When I touch the glass, tons of information about the weight, temperature and slipperiness of the glass is transmitted to the brain via nerves. The force when lifting the glass is on a scale of fractions of a second in my brain. However, I cannot even perceive the electrical storm inside my brain. Let's be careful that we ourselves may not be able to detect the speed at which words come out of our mouth while speaking. But behind the scenes, our brain shapes and produces verb conjugations and this complex order of how the structure of the sentence should be on our behalf. The first person who tried to illuminate the depths of the unconscious was Sigmund Freud. Specializing in neurology plays an important role in the treatment of psychological disorders.
